(iii) The six flat rectangular surface that are the skin of the cube are its faces.Ī cylinder is a solid shape whose top and bottom are circular while the rest of the surface is curved.Ī cone is a solid shape having a plane circular end as the base and whose lateral surface is the curved surface tapering into a point, is called the vertex of the cone.Ī solid (3D) shape that has only a curved surface is called sphere.Ī prism is a solid whose base are identical polygonal shapes (Triangles, Quadrilateral, Pentagons) and other faces are rectangles.Ī pyramid is a solid whose base is a flat polygonal surface and whose side faces are triangles having a common vertex outside the surface of the base. (ii) The 12 line segments that form the skeleton of the cube are its edge. (i) The 8 corners of the cube are its vertices. (iii) The six flat rectangular surface that are the skin of the cuboid are its faces.Ī cube is a special kind of cuboid whose length, breadth, and height are equal. (ii) The 12 line segments that form the skeleton of the cuboid, are its edges. (i) The 8 corners of the cuboid are its vertices. We hope this article gave you required knowledge and information you need.Number of faces, edges and vertices of some solidsĪ closed solid shape that has six rectangular surface is called a cuboid. We also discussed the same with different examples and learnt about Euler’s formula. In this article, we discussed basic properties like vertices, faces, and edges of 3-Dimensional shapes. Whereas 2d shapes have only two dimensions, i.e. Let’s take one more example of a tetrahedron. The software has a comprehensive set of drawing tools to let you easily create vectors from scratch or add to imported data. In geometry, three-dimensional shapes or 3D shapes are solids that have three dimensions such as length, width, and height. It usually works for most of the common polyhedral which we have heard of.įor example, we know that a cube has 6 faces, 12 edges and 8 vertices. It can not be made up of two pieces stuck together, such as two cubes stuck together by one vertex. it can’t be applied for sphere, cylinder or cone. In short, for this formula to work, the shape must not have any holes, and it must not intersect itself. The formula can be used only for closed solids with flat faces. He invented this formula, and hence formula has been given his name. Euler’s formula has been named after a famous mathematician Leonhard Euler. Let’s see vertices, faces and edges of all known 3-dimensional shapes and see how they differ from one another.Įuler’s formula can be used to find out the relation between vertices, faces, and edges. Consolidated table of vertices, faces and edges of 3-Dimensional shapes Knowing the faces, vertices, edges properties of any objects lays the foundation for various industries such as architecture, interior design, engineering and more. For example, a pyramid has 8 edges, and cuboids have 12 edges. In simple language, an edge is a line segment on the boundary, or an edge is a line segment where two faces meet. In geometry, an edge is a line that joins two vertices of a polygon. For example, a cube has 6 faces, and a cylinder has 3 faces. It is also known as the side of an object. FacesĪ flat surface or a plane region that creates part of the boundary of a solid object is known as a face. More specifically, a point where two or more lines of a polygon meet to form an angle or the corner is called vertex. Vertex is a point where two or more curves, lines or edges of a shape meet. The vertex is written as vertices in plural form, usually denoted by capital letters such as E, P, Q, S, Z, etc. For example, the cube has 6 square faces, 8 vertices, and 12 edges, while the sphere has 0 faces, 0 edges, and 0 vertices. The flat sides of a shape that you touch when you hold a shape are known as faces. Lines around the shape are known as edges. The pointy bits or the corners of a shape where edges meet are known as vertices. Let’s see what does each term mean in very simple language. We can say that vertices, faces and edges are the three main properties that define any 3-dimensional shapes of geometry. This tool allows you to learn about various geometric solids and their properties. They are made up of vertices, faces, and edges. In this article, we will discuss various aspects of 3-D shapes with definitions and examples. Sometimes they are referred to as solids too. For example, balls, ice-cream cones, books, etc. All objects are of different sizes and shapes. In our day to day life, we deal with lots of 3-D objects which have length, breadth, and depth. In mathematics, 3-Dimensional shapes are a very important topic of geometry.
